BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply tray for supplying components used for manufacturing electric equipment, automobiles and the like in a manufacturing line.

[0002]

2. Description of the Related Art Conventionally, this kind of component supply tray has been manufactured for each type of component.

[0003]

However, in the above-mentioned conventional apparatus, for example, when a component supply tray is formed of synthetic resin, different molds must be manufactured for each type of component. However, there is a problem in that the manufacturing cost of the components increases, and as a result, the unit price of the component supply tray increases.

[0004] Therefore, an object of the present invention is to realize a component supply tray that can reduce manufacturing costs.

[0005]

Means for Solving the Problems, Functions and Effects of the Invention
In order to achieve the above object, according to the present invention, in the present invention, a box-like body (3) having an opening (34) on an upper surface is provided.
0) and a tray body (20) assembled to the opening (34) and having a first holding portion (23) holding a component (40) formed on a surface thereof, and The body (30) and the tray body (20) are formed separately, and the box-shaped body (30) is capable of assembling another tray body having a different shape into the opening (34). Use the technical means of being configured.

In other words, the component supply tray is individually composed of a box-shaped body having an opening on the upper surface and a tray body assembled to the opening, and the box-shaped body has a shape formed in the opening. Since a different tray body can be assembled, a plurality of tray bodies that can be assembled to one box-shaped body can be shared. Therefore, as the number of tray bodies that can be shared by one box-shaped body increases, the manufacturing cost of the component supply tray can be reduced.

According to a second aspect of the present invention, in the component supply tray according to the first aspect, the tray body (2
0) from the front surface to the back surface, a through hole (21) is formed to project a lower portion (43) of the component (40) held by the first holding portion (23) from the back surface; A lower portion (43) of the component (40) protruding from the rear surface when the component (40) is held by the first holding portion (23) is provided on a bottom surface inside the box-shaped body (30). A technical means is used in which a second holding portion (31) for holding is formed, and the second holding portion (31) is formed so as to be able to hold a lower portion having a different shape.

That is, for example, when a vertically long component is held in the tray body in the same posture, when the component is inserted into a through hole formed in the tray body, the lower part of the component protruding from the through hole is removed. Otherwise, the component may not be held in a stable position. Therefore, it is conceivable to form a second holding portion for holding the lower portion of the component on the bottom surface inside the box-shaped body and hold the lower portion of the component by the second holding portion, but the lower shape of the component is different. If the shape of the second holding portion is changed every time, the manufacturing cost of the box-shaped body increases, but the second shape can hold the lower portion having a different shape.
By forming the holding portion of
Two boxes can be shared. Therefore, as the number of components that can be shared by one box-shaped body increases, the manufacturing cost of the component supply tray can be reduced.

According to a third aspect of the present invention, in the component supply tray according to the first or second aspect, at least one of the box-shaped body and the tray main body is formed of a foamed resin. Use strategic means.

That is, since at least one of the box-shaped body and the tray body is formed of a foamed resin, the hardness of the component supply tray can be changed by changing the expansion ratio of the foamed resin raw material. For example, by increasing the expansion ratio, the entire component supply tray can be reduced in weight. Further, since the hardness can be reduced, it can also serve as a buffer member.

According to a fourth aspect of the present invention, in the component supply tray according to the third aspect, a technical means is used in which the expansion ratio of the foamed resin is 1 to 10 times.

That is, the component supply tray is one to one time.
Since it is molded from a foamed resin having a low foaming ratio of 0, the hardness can be increased, and the strength can be increased. Therefore, even if a heavy component is held, the component supply trays are overlapped, or even if an external force is applied, there is no deformation.

According to a fifth aspect of the present invention, in the component supply tray according to the first or second aspect, at least one of the box-shaped body and the tray main body is formed by injection molding of a synthetic resin. Use technical means that

That is, since at least one of the box-shaped body and the tray body is formed by injection molding of synthetic resin, the properties of the component supply tray can be changed by changing the type of synthetic resin raw material. For example, if a thermosetting plastic is used, a component supply tray that is not easily deformed by temperature can be manufactured.

According to a sixth aspect of the present invention, in the component supply tray according to the first or second aspect, at least one of the box-shaped body and the tray main body is formed by vacuum forming. Use strategic means.

That is, since at least one of the box-shaped body and the tray main body is formed by vacuum forming, it is not necessary to perform printing after production by using a resin sheet that has been printed in advance.

According to a seventh aspect of the present invention, in the component supply tray according to any one of the first to sixth aspects, at least one of the box-shaped body and the tray main body is formed by laser machining. Is used.

That is, since the laser processing is non-contact and does not exert a processing force on the workpiece, when at least one of the box-shaped body and the tray main body is processed with a synthetic resin, processing distortion occurs in them. Difficult to do. Further, laser processing has a very small processing area, so that fine, precise, and complicated shapes can be cut, and surface treatment of narrow portions can be performed. Furthermore, since the optical system can be controlled to draw the trajectory of the laser spot arbitrarily, various shapes can be easily processed. For this reason, it is particularly effective when the component having the above shape is held by the first holding portion formed on the tray main body or the second holding portion formed on the box-shaped body.

According to an eighth aspect of the present invention, in the component supply tray according to any one of the first to sixth aspects, at least one of the box-shaped body and the tray main body has a water jet shape. The technical means of being formed by processing is used.

That is, in the water jet processing, since no heat is generated at the time of processing, there is no influence of heat or processing distortion on the cut surface, so that a component supply tray with high processing accuracy can be manufactured. In addition, the cutting width is very small, the processing accuracy is high, and burrs and burrs do not occur on the cut surface. Further, it is economical because water and abrasives used during processing can be reused. Furthermore, since no toxic gas or dust is generated during processing, it is environmentally friendly.

According to a ninth aspect of the present invention, in the component supply tray according to any one of the first to sixth aspects, at least one of the box-shaped body and the tray main body has an NC machining shape. The technical means that it is formed by machining using a machine is used.

That is, in the machining using the NC machine tool, three-dimensional machining can be performed only by inputting the shape in advance, so that a component supply tray corresponding to the shape of the component can be relatively easily manufactured. it can. In addition, the code | symbol in the said parenthesis corresponds to the code | symbol described in embodiment of this invention mentioned later.

As shown in FIG. 1, the center of each through hole 21 and each through hole 31 is coaxial with each other, and communicates from the through hole 21 to the through hole 31. As shown in FIGS. 4 and 7, the box-shaped body 30 has more through holes 31 formed therethrough than the through holes 21 formed through the tray main body 20. Further, as shown in FIG. 2A, the diameter φ2 of the through hole 31 is equal to the diameter φ1 of the through hole 21.
It is formed larger.

As shown in FIG. 4, the positioning holes 22 for inserting the positioning pins 50 shown in FIG. 3B are formed in the four corners of the tray body 20, respectively. As shown in FIG. 7, positioning holes 32 for inserting the positioning pins 50 are formed at four corners of the box-shaped body 30. Each of the positioning holes 22 and each of the positioning holes 32 are placed above the opening 34 of the box-shaped body 30.

(FIG. 4). That is, the component 40 is held by the holding portion 23, the through hole 21, and the through hole 31. By the way, as described above, since the diameter φ2 of the through hole 31 of the box-shaped body 30 is formed larger than the diameter φ1 of the through hole 21 of the tray body 20, the tip diameter is φ
When supplying parts larger than φ1 and smaller than φ2, there is no need to change the box-shaped body 30 to another box-shaped body.
Only 0 may be changed to a tray body having a through hole 21 through which a component can be inserted.

A through-hole 31 formed in the box 30
Is formed more than the through-holes 21 of the tray main body 20, and if the supply number of the components 40 is larger than the number of the through-holes 21 and less than the number of the through-holes 31, 3
0 does not need to be changed to another box,
Only the tray body may be changed to a tray body having a through hole 21 that is sufficient for the number of parts to be supplied. Further, although the lower part of the component does not reach the bottom surface of the box 30, if the shape is changed, only the tray body 20 corresponding to the shape may be manufactured, and the box 30 is manufactured. No need to do. In this embodiment, the tray body 20 is formed by laser-processing an acrylic plate-like member, and the box-like body 30 is made of foamed resin beads containing an antistatic material at a foaming ratio of 3 times. It is formed by foam molding. Further, a round nut is used for the positioning pin 50. Further, the width L1 is 288 mm and the depth L

mm, and the diameter φ2 is 12.0 mm. further,
The diameter of the head 42 of the component 40 is 14.3 mm, and the diameter of the nozzle body 43 is 9.0 mm.

(1) As described above, if the component supply tray 10 according to the above embodiment is used, even if the shape or number of components is changed, only the tray main body 20 needs to be changed. Therefore, a plurality of tray bodies 20 that can be assembled to one box 30 can be shared. Therefore, the manufacturing cost of the component supply tray 10 can be reduced. (2) Further, since the box-shaped body 30 is formed of a foamed resin, the component supply tray 10 can be reduced in weight. (3) Furthermore, the expansion ratio of the expanded resin is as low as 3 times,
Since the hardness is high, the strength can be increased. Therefore, a heavy component can be held or the component supply tray 1 can be used.
It is difficult to deform even when 0s are overlapped or an external force is applied.

(4) Further, since the shape of the tray body 20 is formed by laser processing, the laser processing can take advantage of the advantage of non-contact. Therefore, since no processing force is exerted on the tray body 20,
Processing distortion hardly occurs. In addition, since the laser processing has a very small processing area, even if the shape for holding the component such as the through hole 21 is fine, precise, complicated, or narrow, it can be easily processed to that shape. . Furthermore, since the optical system can be controlled and the trajectory of the laser spot can be arbitrarily drawn, various shapes can be easily processed. (5) Further, since the box-shaped body 30 is formed of foamed resin beads containing an antistatic material, the box-shaped body 30 is hardly charged with static electricity.

The component supply tray 10 can be suitably used when the component 40 to be held is short in the vertical direction and can be sufficiently held only by the through hole 21 of the tray body 20. When the shape of the part is changed, only the tray body 20 needs to be replaced. In addition, when the lower part of the component is used to hold a plurality of types of components having a shape projecting downward from the through hole 21, the length of the component projecting downward from the through hole 21 is the longest. In order to be able to hold the parts,
What is necessary is just to set the depth of the bottom of 0, and it is not necessary to change the box every time a part is changed.

(2) In the above embodiment, the case where the expansion ratio of the foamed resin is set to 3 times has been described.
It can be set arbitrarily within the range of times. That is, by making the expansion ratio smaller than 3 times,
A box-shaped body having a higher hardness than the box-shaped body can be formed. By making the box-shaped body larger than three times, a box-shaped body having a lower hardness than the box-shaped body 30 can be formed. It is desirable that the expansion ratio be set to an optimum value according to the weight of the part and the application. (3) In the above-described embodiment, the case where the tray main body 20 is formed of acrylic is described. However, the tray main body 20 may be formed of synthetic resin or foam resin other than acrylic. Also in this case, it is desirable to set the expansion ratio of the foamed resin to an optimal value according to the weight of the component and the application. For example, in the case of an application for supplying parts to a robot in a robot assembly line, a certain degree of hardness is required because the hand portion of the robot may come into contact with the surface of the tray body 20. To the desired expansion ratio.

(4) At least one of the tray body 20 and the box-shaped body 30 can be formed by injection molding of a synthetic resin. According to this, the properties of the component supply tray can be changed by changing the type of the synthetic resin raw material. For example, if a thermosetting plastic is used, a component supply tray that is not easily deformed by temperature can be manufactured. (5) At least one of the tray body 20 and the box-shaped body 30 can be formed by vacuum forming. According to this, it is not necessary to perform printing after manufacturing by using a resin sheet printed in advance.

(6) At least one of the tray body 20 and the box 30 can be formed by water jet processing. According to this, the advantage that no heat is generated at the time of the water jet processing can be utilized. Therefore, since no influence of heat or processing distortion occurs on the cut surface, a component supply tray with high processing accuracy can be manufactured. In addition, the cutting width is very small, the processing accuracy is high, and burrs and burrs do not occur on the cut surface. Further, it is economical because water and abrasives used during processing can be reused. Furthermore, since no toxic gas or dust is generated during processing, it is environmentally friendly. (7) At least one of the tray body 20 and the box-shaped body 30 can be formed by processing using an NC machine tool. According to this, machining using an NC machine tool:
The advantage that three-dimensional processing can be performed only by inputting a shape in advance can be utilized. Therefore, the component supply tray corresponding to the component shape can be manufactured relatively easily.
